Airtac PB Pen-type Cylinder PB16X40R
The AirTAC Airtac PB Pen-type Cylinder PB16X40R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 40mm stroke. Its slim round barrel and back cover are stainless steel, the M5×0.8 ports keep plumbing compact, and the fast, low-friction piston suits high-cycle small-part handling.

About the Airtac PB Pen-type Cylinder PB16X40R
The AirTAC PB16X40R is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments without adding unnecessary bulk to your end-of-arm tooling. Delivering a robust 100.5 N push and 90.7 N pull at 0.5 MPa, this 16 mm bore unit is the largest force class in the PB family.
This specific configuration includes an R axial air inlet for straightforward in-line plumbing and uses an M5x0.8 port. It operates at speeds from 50-800 mm/s and relies on a fixed TPU bumper at each end to decelerate the piston near the stroke limits. Because the bumper is not adjustable, high-speed cycles with heavy tooling may require metering out the exhaust or adding an external shock absorber to prevent hard bottoming.

Specifications follow the official AirTAC PB pen-size datasheet. Piston rod and barrel are stainless steel. Confirm bore, stroke and back-cover option against the product label before installation.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 N |
Values are taken from the AirTAC PB thrust table. Because pull acts on the rod-side annular area, pull force is always lower than push. Actual usable force is reduced by friction — size with a margin.

Where the Airtac PB Pen-type Cylinder PB16X40R Is Used
PCB Depaneling Jig
Actuates a routing blade fixture on an electronics assembly line, utilizing the 100.5 N push force to cleanly separate printed circuit boards within a tight machinery footprint.
Carton Flap Folder
Tucks small corrugated box flaps on a continuous packaging conveyor, where the compact SUS304 body resists occasional washdown moisture and the R axial inlet keeps plumbing flush against the frame.
Light Pick-and-Place
Drives a small vacuum gripper on a cartesian robot to lift 5 kg electronic housings vertically, relying on the 40 mm stroke for fast, repetitive transfer between processing belts.
Is the Airtac PB Pen-type Cylinder PB16X40R the Right Cylinder?
Selecting the PB16X40R places you at the top of the PB family's standard force range. If you need slightly less force, stepping down to the 12 mm bore yields 56.5 N push at 0.5 MPa; as the largest standard option, there is no larger bore available in this specific pen-size series. A practical safe working load for this 16 mm model is about 60 N (roughly 60% of the 100.5 N theoretical output at 0.5 MPa), which equates to lifting a 5.1 kg mass vertically with a sensible 2:1 safety margin. Keep in mind the thin 5 mm rod is built for coaxial thrust, so if your application involves off-axis loads, incorporate an external linear bearing to prevent side-loading damage.
When ordering, confirm the 16 mm bore, 40 mm stroke, M5x0.8 porting, and the R axial inlet configuration. This variant does not include a sensor magnet. Note that a standard double-acting cylinder like this will drift and cannot hold a load if air pressure is lost or the valve is centered; applications requiring fail-safe positioning will need an external rod lock or mechanical stop.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Slim pen body vs. a standard round cylinder
- ✓ Back cover: CB / U / R inlet direction
- ✓ Magnet (S) for sensors?
- ✓ Mounting: LB / FA / CJ or front thread
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
- check Fit dust caps to ports during long-term storage.
- check Installation by qualified personnel per AirTAC docs.
Airtac PB Pen-type Cylinder PB16X40R FAQ
This 16 mm bore double-acting cylinder provides 100.5 N push and 90.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, the output is 140.7 N push and 126.9 N pull. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters; this bumper is not adjustable or field-tunable. Additionally, the cylinder does not inherently hold its load if air is lost or the valve is centered, so an external stop or rod lock is required for fail-safe positioning.
